I have looked at many but not seen (or noticed most likely!) that drainage hole.
Interior door panels I have seen two types, the most common one with the flat/straight wood beam and the curved type which seems to be a very early one and like the prototype style - this seems to be the rarest version I have seen.
Mine is quite an early car and has the straight styled card.
Roofs are a mine field, I dread to think how many sub-variants there are of the roof types..
